OK... I think I'm starting to understand. You just need to reshuffle the lines so that the A-msg-B is followed by B-msg_msg-A.

Try this. Not super efficient, but should work:
Code:
IFS=',' 
while read src msg dst ; do 
  [[ $msg =~ _ ]] && continue 
  echo $src,$msg,$dst 
  grep "${dst},${msg}_${msg},${src}" responses.txt
done < responses.txt

where responses.txt is your input file

file2dgr

FILE2DGR(1)							  DGR executables						       FILE2DGR(1)

NAME

       file2dgr - DGR transmission test program

SYNOPSIS

       file2dgr remoteHostName fileName [nbrOfCycles]

DESCRIPTION

       file2dgr uses DGR to send nbrOfCycles copies of the text of the file named fileName to the dgr2file process running on the computer
       identified by remoteHostName.  If not specified (or if less than 1), nbrOfCycles defaults to 1.	After sending all lines of the file,
       file2dgr sends a datagram containing an EOF string (the ASCII text "*** End of the file ***") before reopening the file and starting
       transmission of the next copy.

       When all copies of the file have been sent, file2dgr prints a performance report:

	       Bytes sent = I<byteCount>, usec elapsed = I<elapsedTime>.

	       Sending I<dataRate> bits per second.

EXIT STATUS

       0   file2dgr has terminated.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       Diagnostic messages produced by file2dgr are written to the ION log file ion.log.

	   ION system error.  Check for earlier diagnostic messages describing the cause of the error; correct problem and rerun.
